Dev-C++ is based on gcc and uses .a, not .lib; from where did you
obtain that precompiled library? If it was not produced by Dev-C++,
it is useless in this case.

You need to do the following:

(1) Add 'sample.c' to the project.

(2) Specify the glpk include directory in 'Project Options/Directories/
    Include Directories'

(3) Specify the glpk static library 'glpk.a' in 'Project Options/
    Parameters/Linker' using the button 'Add Library or Object'.

Then all will work.

I successfully compiled glpk 4.10 with Dev-C++ 4.9.9.2; so if you need
the library 'glpk.a', I can post it to you.
